Istiophorus platypterus (?) trying to take bait

A good friend of mine, who uses electronic device to monitor fish (bio-logging) has a grad student interested in sailfish (カジキ). His grad student fitted a number of specimens with a video data-logger to try to figure out what and how they eat.

Anyways, I found a cool video that puts a camera on bait to take  look at how the fish attack the bait. Notice how the fish is using its dorsal fin and upper jaw.
